Product classification
HS code for Rock wool insulation: 6806.10
Slag wool, rock wool and similar mineral wools (including intermixtures thereof), in bulk, sheets or rolls.
Classification of rock wool insulation under HS 6806.10
Rock wool insulation is classified under HS code 6806.10. This code is found in Chapter 68, which covers articles of stone, plaster, cement, asbestos, mica, or similar mineral materials. Heading 6806 specifically includes slag wool, rock wool, and similar mineral wools, including intermixtures thereof, in bulk, sheets, or rolls. The classification is determined by the mineral origin of the fibers. Rock wool is produced by melting basaltic rock and other minerals at high temperatures and then spinning the molten material into fibers. This material is widely used for thermal insulation, fireproofing, and acoustic dampening in residential and industrial construction. The HS code 6806.10 specifically targets the primary forms of these mineral wools before they are further fabricated into complex composite articles. The classification logic groups these materials together because they share similar physical properties and manufacturing processes, distinct from synthetic or organic insulation materials.

Codes often confused with 6806.10
Common mistake. Rock wool is frequently misclassified under HS code 7019, which is reserved for glass wool and fiberglass products. While both are mineral-based fibers, the HS system distinguishes between glass-based fibers (Chapter 70) and stone- or slag-based fibers (Chapter 68). Another common error is using 6806.90, which is a residual category for other heat-insulating or sound-insulating mineral materials; however, if the product is primarily rock wool, 6806.10 is the more specific and correct code. Additionally, expanded minerals like vermiculite or perlite fall under 6806.20, not 6806.10.
Top exporters and importers of HS 680610 (the code used for rock wool insulation), 2025

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
